GUSTAV J. LANGE, 0F EAU CLAIRE, WISCONSIN MARKING ATTACHMENT FOR CANNING-MACHINES.

Specification of Letters Patent." Patented Sept. 20, 1910. Application filed November 26, 1909. Serial No. 529,996.

To all whom it may concern:

Be it known that I, GUsrAv J. LANGE, a citizen of the United States, residing at Eau Claire, in the county of Eau Claire and State of Wisconsin, have invented certain new and useful Improvements in Marking Attachments for Canning-Machines, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved attachment for canning machinery whereby cans may be rovided with identification numerals or %ures as they are passed through the sol ering machines to be placed in the retort kettles or other cooking devices.

The primary object of the present invention is to provide a very simple attachment of the above character whereby the cans may be provided with identification marks as they are carried by a suitable conveying belt between a cylindrical marking pad and a rotatably mounted guide roller.

Another object resides in the provision of suitable means for supplying ink to the marking pad, the inkin member being adjustably disposed wit relation thereto whereby the amount of ink supplied may be suitably regulated.

With these and other objects in view, the invention consists of the novel construction, combination and arran ement of parts hereinafter fully describe and clalmed, and illustrated-in the accompanying drawings, in which Figure 1 is a side elevation of'a marking attachment constructed in accordance with the present invention; Fig. 2 is a top plan View thereof; Fig. 3 is an enlarged transverse section takenon the line 3--3 of Fig. 1; Fig. 4 is a similar view taken on the line 4-4 of Fig. 1; Fig. 5 is a detail perspective view of the supporting frame; and Fig. 6 is a similar view of the marking roller.

In the process of canning peas, beans, or other vegetables and fruits, the cans are passed through a series of machines which rst fill the same with the material and then place a cap or cover thereon and finally close said cover by soldering the same to the can before the can is kettles or other devlces provided for cockpassed into the retort ing the contents thereof. It is customary to rovide suitable identification marks wherey the packers will be able to distinguish between the various grades of the same articles which are put up by the same company, and also to indicate thereon the particular series of machines through which the can passed and the year in which the same was packed. By providin the identifyin numerals or letters, it wil be possible to pl ace the responsibilit for any defect in the packing of the material which is the result of reckless or careless work on the part of the inspectors who are charged with the duty to see that the cans are perfectly sealed before leaving the machines which are under their immediate supervision.

In the attainment of the above ends I proattached to an arm 6 secured to the machine ,by means of the bolts 7. The arm 6 is disposed in a recessed portion of the frame between the ends thereof and below the upper surface so as to permit of the passa e o the can conveying belt between the mar in roller pad and the guide roller. The guide roller 8 is preferably formed of heavy wood and is disposed upon a s uare shaft 9 which extends throu h one end of the supporting frame 5. T e guide roller is vertically movable upon the shaft 8 and may be lifted from the same and another placed thereon in accordance with the size of the cans being marked. This shaft has keyed or otherwlse secured to its lower end a bevel inion 10 which meshes with a similar pin- 1on 11 carried by the horizontally disposed drive shaft 12. This shaft is sup orted in suitable bearings 13 integrally ormed with the frame 5 and dependmg therefrom. The lower portion of the shaft 9 which extends through the end of the su porting frame is cylindrically formed as s own at 9' so that the shaft will have free rotative movement therein. It will be noted that the guide roller 8 is of such diameter that the same extends over the recessed portion of the sup orting frame. A shaft 14 similar to the s aft 9 is vertically positioned through the opposite end portion of the frame and the rectangular portion of said shaft carries the roller 16 on whicha rubber marking ad 17 is secured. The marking roller 16 is also adapted to be lifted from.

its shaft 14 in a manner similar to the guide roller 8 so that it can be replaced by other rollers carrying difierent designating char acters when desired. This pad may be secured to the wooden roller 16 by means of any suitable adhesive material and is formed with the vperipheral ribs or rldges 17 These ridges indicate the size of the peas or 'other material contained within the can.

These peas are graded by all packers, usually into six difierentsizes. The lines whlch are marked on the can by the ribs 17 are indicative of the grade of peas contained therein. As shown in the drawings the rubber marking pad is provided with two such ribs thereby showing that the second size of peas is contained in the can. The pad is also provided with the raised letters which indicate the line of machines through which that particular can passed, the name of the packing company and the yearin" which the goods were packed. An illustrated example is shown in the drawlngs 1 wherein the letter A represents the line of letter b represents the year in which the goods were packed. Every year a different letter is provided thereby necessitating the change of the marking rollers yearly. In this manner when the goods are packed in the warehouse, if peas of different grades are inadvertently mixed, they may be readily segregated by noting the number of lines on the can which indicate the particular grade of goods.

In order to ink the rubber marking pad, I provide the roller 18 on which thefelt covering 19 is secured. A shaft 20 extends through this roller and is adjustably mounted in an L-shaped bracket 21 which is secured to the end of the supporting frame'5. This bracket is formed with a longitudinal slot 22 through which the lower end of the shaft 20 extends. Nuts 23 are threaded upon the shaft 20 on opposite sides of the bracket plate whereby the shaft is rigidly supported.

therein. The bottom of the roller 18 is formed with a central recess 24 which is of sufiicient depth and diameter to permit of the free rotative movement of the roller upon the shaft. This'roller is rotated by the frictional contact of the marking roller therewith, and as said rollers are rotated the ink which has previously been supplied to and absorbed by the felt covering 11) is taken up by the marking roller, so that the letters and ribs thereon will leave a clear and distinct impression upon the periphery of the cans as they pass between the guide roller 8 and the marking roller. In Fig. 1 the can A is shown passing between the rollers after having been provided with the identification marks. The can is carried upon the flexible conveying chain or belt 25, which as previ ously stated passes through the centrally recessed portion of the frame. A band wheel 26 is carried by the outer end of the drive shaft 12 and a drive belt 27 extends thereover and to the-power shaft of the engine or motor. A pinion 14 is secured to the lower end of the shaft 14 and is engaged by a similar pinion 28 carried by the shaft 12 whereby rotative movement is imparted to the rollers 8 and 16 in a common direction.

From the foregoing it will be seen that I have provided an attachment for canning machinery which is of great utility, is

highly efiicient in its operation, and maybe produced at a minimum expense. The guide roller 8 and the marking roller 16 may be removed and others positioned-on the shafts 9 and 14, respectively, when cans of varying diameters are to be marked. The amount of ink supplied to the marking roller may be regulated to a nicety by adjusting the inking roll upon the bracket plate 21 so that the frictional engagement between the same and the marking roll is increased or decreased whereby exactly the proper amount of ink may be taken u by the marking roll and comprising a supporting frame having a centrally recessed portion adapted to receive an endless carrier, shafts extending vertically through the opposite ends of said frame, a guide roller removably mounted on one of said shafts, a marking roll removably mounted on the other of said shafts, a bracket extending laterally from the'frame, an inking roller longitudinally adjustable on said bracket having frictional engagement with said marking roll and adapted to be ro tated thereby, said marking roll being provided with identifying numerals or letters I In testimony whereof I hereunto aflix my and peripheral ribs, pinions secured to the signature in the presence of two witnesses. lower ends of saul shafts, and a drive shaft GUSTAV LANGE mounted in hearings on said frame, said 5 drive shaft carrying pinions engaging with the first named pinions substantially as and for the purpose set forth.
